GRAIN ELEVATOR AND BLGWER.

Applcatign filed July 9, 1924.

The present invention relates to an apparatus lor unloading grain trom awagon y and elevating it to a granary and incidental- Il (l ly forcleaning grain from dust, chatl1 and other foreign matter mixed with thegrain. lt is mainly intended for cleaning small gii'ain, such as wheat,oats, barley7 rye and shelled corn.

The apparatus consists ot a belt or chain conveyer 'for lifting thegrain to a certain level from where it is dropped past a strong aircurrent produced by a tan. In this manner all dust and foreign matterwill be removed and the cleaned grain collected at the iront end of theapparatus.

ln the accompanying drawings, one embodiment of the invention isillustrated, and

Figure 1 is a side elevation ot' the grain unloading and cleaningapparatus;

Fig. 2 is a vertical longitudinal section thereof;

Fig. 3 is a top plan view, and

Fig. l is a section on the line int of Figure 1. v

In the drawings, the reference Vnumeral represents a base for theapparatus and the reference numeral 11 represents a casing for a tan 12enclosed therein. The casing is ot cylindrical shape and is providedwith an upwardly directed spout 13 which has a grain-receiving opening14 on its upper side adjacent thel mouth of the spout. Almost directlyunder this opening is furnished a discharge opening 15 where the spoutjoins the casing. Back of this discharge opening 15 is provided anupstanding partition or lip 16. V

The tan 12 is mounted on a horizontal shaft 17 which extends in bothdirections through the side walls 18 ot the casing. The shaft issupported in suitable bearings 19 one )n each side of the casing, andthe side walls 18 are provided with central apertures 2O of considerablygreater diameter than the shaft for the intake of air. The fan has aplurality ot radially directed arms 21 upon which the ian blades 22 areirmly secured, as by bolts 8 or the like. lu the drawings six; bladeshave been shown, but it is evident that any other cwritable number maybe -selected. rl`hese blades are substantially of the fullwidth of thecasing and almost touch the cylindrical wall ot the casing. They aremounted to revolve in clockwise direction, as seen in Fi lure 2 andindicated by arrow X, so that air drawn in through the side Serial No.725,033.

openings 2O in the casing will be projected through the spout 13 whichis inclined about forty-live degrees against the horizontal plane.

Une end of the shaft 17 carries a pulley 24 adapted to receive a beltconnected with a suitable source of power for revolving the fan. Theother end of the shaft 17 carries a sprocket wheel 25 which is smallerthan the pulley and the use oit which will presently be described.

On top of the casing is secured a channel or trough 2G for a conveyer27. The bottoni 28 ot the trough extends some distance to the rear ofthe 'fan casing 11 and has a transverse wall 29 at its lower end.Similarly another transverse wall 30 is provided at the upper end oit'the tr-ough at which place, however, the bottom 28 terminates even withthe receiving opening 111- in the spout. Above this opening is carried aspindle 31 having a sprocket wheel 32 for a conveyer chain The lower endof the conveyer chain is taken around a second sprocket 84 mounted on aspindle 35 at the lower end ot the trough, suitable bearings beingprovided ior these spindles in the trough. The conveyer is of the rakerchain kind. That is to say, a plurality of rakes 3G are secured inspaced relation on the chain 3S. rihese rakes consist of square sectionbars which extend in transverse direction from side to side of thetrough, as best seen in Figure 3. lt is evident that instead of thisraker chain conveyer an ordinary belt conveyer may be used i1 sodesired.

The lower end of the trough 26 is 1provided. with side walls 37 ot'greater height than the rest ot the side walls of the trough and betweenthese side walls 37 is carried revolubly a spindle 88 upon which ahopper 39 is hinged. This hopper extends rearwardly from the trough 26and is ot similar con- -revolubly mounted at the rear end ot the hopper39. Between the upper Vand lower runs of the conveyer 27 and L11 areinserted boards L15 and 46, respectively, which are 1ntended to sustainthe weight oit the conreyer and the grain Carried between the ralies.The hopperl 39 is open on its upper Side and at its tro-nt end ain` iSprovided with Quart l? at its rear end adapted to conduct the `grainwhen thrown into the hopper so that it will tall between the raltee #i8upon tht` board 46. The hopper has suitable hinged legs 49 for adjustingthe height oit the rear end thereof and, when not in use, the hopper maybe Swunir,l around the axis ot the spindle 38 to told over the troughThe Spindle 3l at the 'trout end ot the trough 26 carries a sprocketwheel 5() which is connected by ineans ot a chain 5l with the sprocketwheel on the shaft i7. By this ineans the confeffer Q? is operatedeinmitaneonsly with the turning oi the tau l2. A chain runs over theSprocket wheeiS :l and 54 niounted, respectively, on the epindleeI andIt will thus be sven that, whenever the eonreyer is moving. the conveyoril in the hopper will also more and the rangement is inade so that theupper runs ot the conveyors proceed in the toi-ward direction of theapparatue when the jan lil is revolvinp,l in clockwise direction,indicated by the arrow X in Figure 2.

The apparatus ie used in the vlillowing manner. Ae soon as the tan. hasbeen started and the Conveyors 2T and l are in inotion, grain is thrownin at the guard All of the hopper, thusdepositing the saine between therales 48 upon the board 46 thereol. This grain ie gradually carried tor-1ward by the conreyer and dumped upon the board between the ralces 36 otthe main conveyor which carries it ul'iwardlj,Y to the upper end ot thetrough when, the `airain actuated by gravity proeeeos in a downwarddirection through the receiving' opening il ot the spout 13. AS the tanat thisl time rotates, a strong air current will be driven through thespout 13 and through the fallingr grain, thus carrying away dust, eliafiand other foreign matter that might be niixed with the grain. The grainwill tall down upon the bottoni of the spout l-' and slide down thesaine and out through the dien charge opening l5 where it may hecollected and stored. rthe partition or tongue 1G will prevent any graintroni fallingl on the fan itsell' and prevent the 'tree workingot thelatter.

Haif'ing' thus described the invention, I claini:

In a grain separator, a main conveyor cluding` a trough extending at anupward 1neline and having' a bottoni lirn'ied with an outlet adjacentits upper end, side walls, au upper entV wall, and a lower end wall ofgreater height than the side walls, auxiliary side wall Sections securedagaint the outer faces ot the lower port-ions oi said side wallsl andprojecting` upwardly above the lower end wall and cooperating therewithto torni a hopper tor the lower end portion ot' the trough, ine-ans formoving `grain upwardli,r through said trough tor pas'sf ge out ot theoutlet adjacent the upper end thereof, and an auxiliary conveyorincluding a trough pirotall7 mounted at one end between Said auxilituf)7Side wall Sections there said side walls and iu advance ot' said endwall tor Swinging n'ioveinent troni a folded position in overlying`relation to the tiret trough to an extended position with its bottoniresting upon the upper edge of the lower end wall ot the tiret trough,and means t'or moving grain through the auxiliary trough and deliver-ingthe saine into the lower end portion of the niain trough.

In testimony whereof I atlix niv Signature.
